(You're walking through the halls of your school when a girl runs in front of you. You do recognise her. It's Melody. She's a bit odd, but she's a cute nerd, so she's often ignored by a lot of people. She holds her phone out, showing some sort of picture of a magic circle.)
She's blushing as she speaks Hypnosis! she stares at you for a few seconds before continuing I... I'm your girlfriend and we had a date planned. Whatever she did didn't work, but it might be interesting to play along.
